Specification of Letters Patent.

Patented June 10, 1.91 3.

Application filed March 12, 1912. Serial No. 683,400.

To all whom it may concern:

Be it known that I, ANnanw 1*]. Hosea, a citizen of the United States,residing at Washington, in the District of Columbia, have invented newand useful Improvements in Devices for Wixing Salad-Dressing, ot whichthe following is a specification.

This invention relates to mixing and storing devices, and has particularreference to an improved apparatus or device for mixing and storingsalad dressings, and the like.

Coi'isidcrable loss of time and annoyance has heretofore beenexperienced in handling salad, or other dressings since it is necessaryto mix the ingredients in the desired quantities in a receptacle ofsntlicient size, and to then pour the mixed dressing from suchreceptacle into bottles or other vessels which must be placed in arefrigerator, or other cooling chamber to keep the dressing in propereomlition until used, \Vhcn these vessels stand tor any appreciablelength of time the cinnponcnt substances of the dressing becomeseparated, the heavier substances collecting on the bottom of the vesseland gumming or adhering to the bottom and sides of the vessel, making itvery ditticult to thoroughly remix the ingredients when the dressing isto be used.

It the prime object of this invention to provide an apparatus or devicewhich, of itself. possesses all the necessary parts to mix, store, keepin a, cool and proper condition, remix, and to deliver a salad dressingwithout the necessity of providing the separate devices now en'lployed,for performing these several necessary functions, which are removed tromone another and are not particularly adapted for this special usewhereby there is a considerable loss of time and unnecessary labor inhandling the dressing.

Another object of this invention is to provide the device with a mixingmechanism which will thoroughly agitate the contents to insure thedesired and correct proportion oi the ingredients throughout the entiremass ot the dressing during the initial mixing of the dressing, and alsoafter the ingredients have become separated when stored for anyappreciable length of time. This mixing mechanism is designed to set upa current of the liquid flowing from the bottom of the device upward,and to set up a second current of. the liquid flowing from the topdownward to violently agitate the liquid by the meeting o l theseopposing cur rents, and to turthcr create a centrifugal [low oi. the.liquid at the meeting of these two currents to insure further and moreviolent agitation.

This invention has for a further object to provide means for feeding theingredients into the device through a tunnel to substantially thecentral portion oi. the receptacle ot the device without displacing orhindering the operation of the centrally located mixing mechanism.

In the accomplishment of the above enumerated objects, the invention inone cmbodimcnt comprises, broadly, a. casing or cabinet divided into acooling compartment and a packing compartment, and provided with astorage chamber extending partly into both comlmrtments in which isrel'novably carried a receptacle or container into which the ingredientsoi the dressing are poured. This receptacle, or container, contains amixing device operated by a mechanism housed in the cover of thereceptacle for agitating and mixing the ingredients placed in thereceptacle. Provision is made For drawing oll desired quantities of thedressing from the receptacle without removing it from the cabinet, thesame being awomplished by a drainage-cock oi. suitable constructionwhich is carried in the lower end and at one side of the receptacle, andwhich projects through the side of the cabinet. lhe cabinet is providedwith a slot or opening in its side through which the drainage-cockpasses, and which admits ot' the removal and replacementofthereceptaclewithout detaching the drainagecock from the receptacle,means beingprovided for closing the slot to insure the tight sealing of the cabinetwhen the receptacle is in position. The cabinet is provided with asectional and removable cover admitting the removal of the receptacle,and oil independent access to the separate compartments. A funnel ishoused in one side of the top of the receptacle. and has a distributingneck extending across and opening substantially at the eentral portionof the receptacle beneath the top to feed the material into thereceptacle at such a portion.

Other objects and advantages of this invention will appear from thefollowing spe cific description of this embodiment of the invention, andfrom the accompanying drawings, in which:

Figure 1 is a front elevation of the device; 2 is a top plan view of thesame; Fig. 3 is a similar view with the cabinet cover and the upper topsection of the receptacle removed; Fig. 1- is a transverse section takencentrally through the device; Fig. 5 is a horizontal section taken onthe line of Fig. 4:, and with the false bottoms of the cooling andpacking compartments removed; Fig. 6 is a detail enlarged fragmentaryview, partly in section; of ti e sectional top in position on thereceptacle; Fig. 7 is a detail enlarged sectional view, showing indisassembled relation the upper end of the dasher-shaft, and theconnecting part of the operating mechanism with the guide for directingthe shaft into the connecting part; and Fig. 8 is a detail view of thedasher or mixer.

Referring to the drawings, which disclose the present embodiment of thisinvention, the entire device is housed in a casing or cabinet 10,preferably rectangular in form and open at its upper side, and which isprovided with a two-part cover 11 and 12 closing its upper side. Thesections 11 and 12 of the cover are hinged together upon a common pintle13 extending transverseiy across the front and rear walls of thecabinet, the pintle having its ends projecting beyond the walls anddetachably engaging in the upper ends of a pair of registering bracketarms 14 and 14 extending upwardly and being offset outwardly from thefront and rear walls of the casing 10. Preferably, the bracket arm 14Lis provided with an opening receiving one end of the pintle 13, whilethe bracket 1 1 is provided with a slot opening through its upper endforming a socket into which the opposite end of the pintle 13 is adaptedto rest. These bracket arms 14 and 14 engage the opposite edges of thecover of the cabinet and thereby hold the same in registration over thecasing. Each section, 11 and 12, is provided with a finger grip 14:positioned upon its upper side, and by means of which the sections maybe independently raised to open the opposite ends of the casing.

Midway between the ends of the casing 10, but in close proximity to thefront wall thereof is a storage chamber 15 formed by a cylindrical wallupstanding from the bottom of the casing. As will be noted par ticularlyfrom Fig. 2 the front wall of the casing 10 is curved inwardlyconcentric to the storage chamber 15 at the opposite sides thereof toprovide clearance spaces 16 for a purpose hereinafter set forth. Thestorage chamber 15 is provided with a false bottom 17 spaced slightlyabove the bottom of the casing 10 and being provided with circularlyarranged openings therethrough. The front side of the storage chamber 15is provided with a vertical slot or throat 18 extending from top tobottom thereof, the material removed to form the slot 18 being turnedoutwardly and conveying from the opposite sides of the slot to provide apair of inclined flanges or guides 19. The front wall of the casing 10is also slotted in registration with the slot 18, the slot in the frontwall terminating at a point spaced a short distance above the bottom ofthe casing. A slide 20 is removably positioned in the slot of the casingfor closing the same, and is provided with a pair of inwardly extendingwings 21 hearing against the inner opposite sides of the guides 19 tosupport the slide 20 in position, the upper ends of the wings 21 beingpreferably flared to bind the wings against the guides and hold theslide 20 tightly in position.

The casing 10 is provided with a partition 22 extending from the rearwall of the casing to the rear side of the storage chamber 15, and beinglocated toward one end of the casing 10 to divide the easing intorelatively large and relatively small compartments. From thisconstruction it will be observed that approximately two-thirds of thestorage chamber extends into the larger compartment. A perforated falsebottom 23 is arranged in the larger compartment and is spaced slightlyabove the bottom thereof for the reception of ice or other coolingagent, while an imperforate false bottom 24: isdispos'ed in the smallercompartment for supporting measures and the like which are placed in thecabinet, and which are utilized in preparing the dressing.

l Vithin the storage chamber 15 is snugly and removably fitted areceptacle 25 conforming to the cylindrical contour of the inner wall ofthe storage chamber and which is provided with a number of dependingsupporting legs 26 extending down through the openings in the falsebottom 17 of the chamber 15 and resting upon the bottom of the casing10. The central portion of the bottom of the receptacle 25 is depressedto provide a stepped bearing 27 projecting down through the false bottom17 and resting upon the bottom of the casing 10. The upper end of thereceptacle 25 is enlarged and headed at a point slightly above the upper edge of the storage chamber 15 to strengthen the receptacle and toprovide an inner annular shoulder 28 facing upwardly to support a dishedupwardly opening top section 29 adapted to close the receptacle. Theenlarged portion of the receptacle 25 extends a short distance up aboutthe top section 29 to provide a ledge or flange 30 supporting the loweredge of an outer top section 31. The outer top section 30 is in the formof a cap which extends above and over the upper open side of the innertop section 29 to provide a hollow chamber within the top. Suitablefastening means, such as hooks 32, are carried upon the flange 30 andengage outstanding pins or studs 33 carried upon the outer top section31.

A disk 34 is disposed within the inner section 29 and is provided with acentral depending boss 35 having a downwardly flaring central opening,the wall of which forms a guide 36 receiving the upper extremity of themixer shaft 37 and moving the shaft up into true vertical position inplacing the top on the receptacle. Against the upper side of the disk3st, and immediately over the boss 35 is placed a pinion 38 having anangular axial opening communicating with the inner reduced end of theguide 343 and adapted to receive the angular shank 3.) of the n'iixershaft 37 to interlock the same with the pinion. The pinion is providedat its opposite sides with outstanding bosses, the lower one of which isseated in a depression in the disk 34 while the upper boss is receivedin a circular opening formed in a supporting strap -10 arched over thepinion 38 and having its ends secured upon the disk 3st. A gear 41 isarranged against the upper face of the disk 3 tin intermeshing relationwith the pinion 38, the gear 41 being mounted upon an upstanding stud l2can ried by the disk 34L. Centrally arranged upon the upper :tace of thegear 40 is a relatively small bevel gear 43 meshing with a verticallydisposed bevel gear at carried upon a driving shaft 45. The drivingshaft L5 is journaled at one end in the upper end of the stud t) whileits opposite end is mounted in a bearing 1:6 upstanding from the disk34. The driving shaft is so arranged that it extends diametricallyacross the top of the disk 34: above the pinion 3S, and its tree endlocated adjacent to the front side of the receptacle. The inner andouter top sections 29 and 31 are provided with registering openings 47which register with the extremity of the operating shaft 4-5, and whichregister with an opening 48 formed in the slide 20. The extremity of theoperating shat't is formed angular in cross-section :tor the receptionof a eorrespondingly formed head 49 ot a crank handle 50 adapted to turnthe shaft. The head 4:9 is slightly elongated to extend through openings4L8 and 4-7 respectively and engage the angular shank of the operatingshaft.

The receptacle 25 is provided adjacent to its bottom and in its frontside with a drainage cock 51 of any suitable construction by means ofwhich the contents of the re- (:eptacle may be withdrawn in desiredquantities. This drainage cock 51 projects through the vertical slot 18of the storage chamber 15 and through the slot in the front wall of thecasing 10. The lower end of the slide 20 is recessed t0 snugly fit overthe drainage cock 51. and form a tight joint about the same.

For the purpose of holding the inner and outer top sections 29 and 31 incorrect position for registering the openin s -17, and in correctposition with respect to the receptacle 25, the flange 30, and the innerand outer top sections 22) and 31, are provided at one side withinwardly extending beads 51, termed preferably by crimping the sides otthe respective members, which determine the correct positioning of themembers and interfit to hold the same in such position.

The receptacle is designed to carry a mixing device, the same being inthe nature of a dasher having as its main portion the vertical shaft 37.The lower end oil the dasher has a screw propeller 52 suitably securedupon the shaft and adapted for rotation therewith to create an upwardcurrent of the liquid placed in the receptacle. Arranged inlongitudinally spaced relation upon the shaft 37 and preferablyextending in dill'erent directions therefrom are a number oil inclinedpaddles 53, adjustably secured to the shaft 37 by set screws 5 t,adapted to create a downward current of the contents of the receptacle.Arranged between the paddles 5?) and the propeller 52, is a paddle 55,held in adjusted position on the shaft screw 50, which extends in thevertical plane of the shaft and is rotated to throw the contents of thereceptacle centrifugally outward from the shaft 37 and dift'use themeeting currents of the liquid. Thus, when this improved dasher isoperated, the propeller 52 forces the liquid upwardly, the paddles 5?)force the liquid downwardly and the paddle forces the liquid of themeeting streams or currents of the liquid toward the sides of thereceptacle. It is thus noted that the contents ot the receptacle 25 isthoroughly agitated whereby the ingredients of the dressing arethoroughly intermingled and a uniform mass is produced.

The inner top section 29 carries a distributcr 57 preferably in the formof an elbow, one arm oi. which is threaded and extends upwardly throughthe section 29 and through the disk i l-t, while the horizontal armthereof extends toward the central portion of the receptacle and isprovided in its underside with a plurality of outlet openings 58 throughwhich the ingredients are fed to the receptacle. A 't'uunel 5E) extendsupwardly from the vertical arm oi the elbow 57, its upper edge lyinginnuediately beneath the outer top section 31. The top section 31 isprovided with an opening imme diately above the funnel 59 to admit thepouring of the ingredients of the salad dressing into the funnel.

The cover section 12 covers that portion of the receptacle top in whichthe funnel 59 is mounted, and for the purpose of admitting access to thefunnel without raising the cover section 12, an opening is formedthrough the section 12 immediately over the funnel 59, the opening beingnormally closed by a slide 60 movable in ways 61 arranged in parallelrelation upon the section 12 at the opposite sides of the opening. Oneend of the slide 60 is reduced and turned upwardly to provide a lip 62by means of which the slide is operated to uncover and close theopening.

In the use of this improved device a quantity of ice is placed in thelarger compartment, beneath the cover section 12, and about the majorportion of the storage chamber 15. The smaller compartment of thecabinet is adapted to contain the measuring, and such other vessels andimplements as are found necessary in collecting the various ingredientsfrom which the salad dressing is made. When it is desired to mix aquantity of the dressing it is only necessary to push back the slide 60and pour the various ingredients into the funnel 59, the liquids passinginto the elbow 57 and through the openings 58 into the receptacle Thehandle 50 is now applied to the operating shaft 45 by inserting the head49 through the openings 13 and 17 respectively and over the angularportion of the shaft 45, when the handle is turned to actuate the bevelgears 14: and 43 respectively which turn the gear 41 and the pinion 38.As the shaft 37 is connected for rotation with the pinion 33, the dasheris rotated. As before explained, the rotation of the dasher producesopposing currents of the liquid flowing from the opposite ends of thereceptacle and breaks up the meeting streams or cur rents of the liquidof the centrifugal action of the paddles 55. [is disclosed in thedrawings, the paddles employed in the formation of the dasher areprovided with a number of openings extending throughout their lengthsthrough which the liquid passes and which effects the thorough mixing ofthe ingredients.

As is well known, when the dressing is allowed to stand for anyappreciable length of time its ingredients become separated, as thedressing is but a mechanical mixture, and the heavier ingredients fallto the bottom of the receptacle and adhere thereto. It is, therefore, anadvantage to provide the storage receptacle with the mixing mecha nismdisposed and forming part of the same, since when the dressing is to bewithdrawn it is only necessary to attach the operating handle 50 to themechanism in the cover and set the dasher in motion. The dasher, byreason of its peculiar action, removes the adhering ingredients from thewalls and the bottom of the receptacle and efiects the thorough remixingof the dressing prior to withdrawing the same.

lVhen it is desired to remove the receptacle 25 from the cabinet 10 forcleansing or other purposes, the pintle 13 is lifted out of the socketof the arm 1 1 raising the cover, and then the opposite end of the*pintle is released from the arm 1 1 whereby the cover is freed from thecabinet. The hooks 32 are now released from the studs 33 and thecap-section 31 of the top removed from the receptacle. The inner section 29 is now lifted up from the shoulder 28, releasing thedasher-shaft 37 and admitting the withdrawal of the dasher from thereceptacle. The slide 20 is now drawn upwardly to release the wings 21from the flanges or guides 19 to free the slide. The receptacle 25 isnow raised up out of the storage chamber 15, the drainage-cock 51 movingup in the vertical slot 18 and in the slot in the front wall of thecabinet. The reverse operations take place in replacing the parts, thelower end of the dashershaft 3'? being fitted in the stepped bearing 27,and the guide 36 carried by the inner top section 29 positioning theshaft 37, if canted, in the opening of the pinion 33. A draining cock 63is carried through one side of the casing and communicates with thelower end of the cooling compartment through which the collected waterincident to the melting of the ice may be drawn off.

From this embodiment of the invention, it will be seen that the cabinetis so formed as to provide all of the necessary compart ments andoperating mechanism for mixing and storing such liquids as saladdressings, and that each part and mechanism are peculiarly adapted toperform the various functions necessary in mixing and making thedressing.

it will be understood that this disclosure is but one embodiment of thisinvention, and that various detail changes in the construc tion andarrangement of the parts may be had without departing from the spirit ofthis invention, the scope of the invent-ion being defined by thesubtended claims.
